Well, on my truck the stock front door speakers are 6x9s, and I want to install some Pioneer rev 6.5"s. I can get some well made plastic mounts for 45 shipped but I then realized I have some scrap 3/4" mdf in the shed. Would it hurt anything at all to make these out of MDF?

This is what I'm making:

Go for it. It will work perfectly fine, and save you an insane amount of money considering you were going to pay $45 for something that costs about $5 to make.

3/4 MDF is actually better and much much cheaper... use clay or silicone to seal and make it airtight

here are some pics of mine i made to put 6.5"s in a ford 5x7 hole

Make sure that you waterproof the mdf with a sealant. Doors are a very damp environment.

I have some bedliner in a spray paint can that I will coat it with. I coated my MDF radio enclosure mounted on my ATV with the same bedliner and it's gotten washed and rained on, even coated with mud plenty times and it's never gave up on me.

Thick plastic is just as acoustically inert as MDF. MDF holds no benefits over the pictured product other than cost.

what if the plastic is hollow?

Depends on the density of the plastic and the wall thickness. Those in the pic appear to be cut from solid stock.

If you did go with the plastic spacers I would put something in between the doors and the spacer like dampening material of some kind

I'm gonna build some MDF ones as soon as I decide to buy the 6.5"s.

If the door is properly deadened, it should be an additional issue with either.

What should I put between the spacer and the door?
